Silvery lutungs breed year round, with no clear breeding season, although each female typically gives birth no more than once every 18 to 24 months. The female attracts the male by making side-to-side motions with her head, and copulation may occur several times during a bout. Unusually, females have been reported to reach menopause in the wild, and may survive up to nine years after last giving birth. The female gives birth to a single young after a gestation period of 181 to 200 days. The young weigh about 400 grams, measure about 20 centimetres and are well developed, with a strong grip for holding onto the mother. Silvery lutungs are born with orange fur, and with white hairless skin on the face, hands, and feet. The skin rapidly changes to the dark adult colour, but the fur does not reach the adult pattern for three to five months after birth. The young are cared for by females communally, and are not weaned for 18 months, even though the biological mother stops lactating after just 12 months. The young are sexually mature almost as soon as they finish weaning, and, on average, females first give birth at 35 months of age
